END-GATE-LOGKING MECEANISM.

Specification of Letters Patent.

Patented Apr. 2a, 191?.

Application filed August 16, 1916. Serial No. 115,227.

To all whom it may concern:

it known hat I, .Annnnr M. NnLsoN, a citizen of the United States, residing at Doland, in the county of Spink and State of South Dakota, have invented certain new and useful Improvements in End-Gate- Locking l /l'echanism; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

lhis inven ion relates to locking mechanism for that type of wagon end gate con sisting of a pair of foldable sections having a transversel extendin element associated with one of the sections and adapted to we tend across the meeting edges of the sec tions, when the sections are in operative posit-ion, and an object of the invention is the provision of asimple, durable and cilicient locking mechanism that can be conveniently associated with the other gate section and operatively engage the element carried by the first-mentioned gate section, when the sections are in operative position so as to sections.

Other objects will appear and be better understood from that embodiment of my invention of which the following is a specification, reference being had to the accompanying drawings, forming a part thereof, in which:

Figure 1 is an outer side elevation of the end gate showing the locking mechanism applied thereto.

Fig. 2 is a section taken on the line 22 of Fig. 1.

Fig. 3 is a perspective view of the locking bolt removed from operative position.

Referring to the drawings in detail, the letter A designates the rear end of a wagon body, B, the end gate, which is formed of hingcdly connected sections 0 and D.

An elongated plate 1 has one end secured to the section B, and said plate extends across the meeting edges of the sections C and D, and has its opposite end restricted, as shown more clearly in Fig. 1 of the drawings. Associated with the restricted end of the plate 1 is a Y-shaped element 2, the sides of which have connection with the restricted end of the plate 1, by means of fastening elements 3, and the stem of the Y-shaped element extends a considerable prevent accidental folding of the a distance, as shown in Fig. 1, beyond the terminal of the restricted end of the plate 1.

Fiecured to the section C of the end gate, and at a point adjacent the outer edge thereof, is an elongated vertically disposed plate This plate 4: is provided with a pair of apertured ears 5 that are struck outwardly from the plate adjacent the upper end thereof, and is also provided with a vertical series of a ertured ears 6, 7 and 8, which are likewise struck outwardly from the body of the plate and bent upwardly as shown in Fig. 1, and alined with the space between the ears 55. W hen the sections 6 and D of the end gate are in operative position, as shown in Fig. 1, the stem of the Y-shaped element 2 is received by the space between the ears 7 and 8 on the plate a, and engages the plate as shown in Fig. 2 of the drawings. A reciprocating bolt 9 is received by the openings or apertures in the ears 6, 7 and.8, and when the stem of the Y-shaped element 2 is in the position shown in Figs. 1 and 2, the bolt 9 engages thereagainst and prevents outward movement of the (shaped element, hence preventing folding of the sections C and D. The upper end of the bolt 9 extends between the ears 5 and is terminally provided with a transversely extending sleeve 10, that is disposed above the ears 5 and located at the opposite ends of the sleeve 10 are the upper ends of a pair of vertical links 11, the said links 11 having openings therein, alining with the bore of the sleeve 10, for the reception of the cotter-pin 12. A U- shaped handle 13 has the sides extended inwardly and terminally extended in parallelism and positioned between the ears 5, and the sides engage the inner sides of the ears 5 and are provided with trunnions 14 journaled in the openings or apertures in the ears 5, so as to admit of the handle 13 having vertically swinging movement on the plate 4. The sides of the handle 13 are also provided, at points below the trunnions 1a, with inwardly extending trunnions 15 that are received by transverse slots in the lower ends of the links 11.

When it is desired to fold the gate sections C and D, so as to admit of the removal of the gate 13, the handle 13 is swung upwardly resulting in vertical lifting movement being imparted to the links 11, which will cause the bolt 9 to be moved upwardly to a point where the lower end thereof will lie above the ears 7. The section G of the gate is then swung inwardly, in the usual manner so as to admit of the gate B being detached from the operative position.

A vertically disposed contractile spring 16 has the upper end thereof attached to the cotter-pin 12 and the opposite or lower end connected to the plate 4. This spring 16 tends to return the bolt 9 to normal position after the handle 13 is released, and also prevents accidental upward movement of the bolt 9 when the same is engaging over the end of the stem of the Y-shaped element or body 2. 7

It is evident that various changes might be resorted to in the construction, form and arrangement of the several parts without departing from the spirit and scope of the invention; hence I do not wish to limit myself strictly to the structure herein described and claimed.

Having thus described my invention, what I claim is.

l. The combination with an end gate formed of a pair of foldable sections, and an element having one end connected to one of the sections and having its other end adapted to engage the other section when the sections are in unfolded position, of a plate mounted on the other section of the gate, a (shaped element carried by the other end of the element and having the stem portion thereof extending beyond the free end of the element and adapted to engage the plate when the sections arein unfolded position, a bolt slidably associated with the plate for engaging the stem of the Y-shaped element when the sections are in unfolded position, and a manipulating element carried by the pl ate and having connection with the bolt.

2. The combination with an end gate formed of a pair of foldable sections, and an element having one end connected to one of the sections, and having its other end eX- tending across the meeting edges of the sections, of a plate carried by the other section, a vertical series of apertured lugs struck therefrom, means carried by the element and adapted to be received by the space between adapted to extend across the meeting edgesof the sections when the sections are in unfolded position, of a plate carried by the other section of the gate, means carried by the element for engaging the plate when the sections are in unfolded position, a bolt slidably associated with the plate for engaging over the mentioned means, when the gate sections are in unfolded position, a sleeve carried by the upper end of the bolt, a manipulating element pivoted to the plate, links operatively connected to the sleeve and the manipulating element so as to effect sliding of the bolt when the manipulating ele ment is moved in one direction, and means for effecting the return of the manipulating element, links and bolts to normal position after the manipulating element is released. 4:. In locking mechanism for folding gate sections, the combination with a plate carried by one of the sections, lugs formed on the-plate, a bolt slidably associated with the plate and operable between the lugs, means carried by the other gate section for engaging in rear of the bolt when the sections are in unfolded position so as to prevent folding of the sections, a U-shaped manipulating element having the sides thereof pivoted between the lugs, and means for connecting the manipulating element to the bolt, where by to effect sliding of the bolt when the manipulating element is operated.

In testimony whereof I a-ffix my signaturein presence of .two witnesses.
